Cafe wall illusion
Cafe wall illusion. This illusion is so named because it was first noticed on a tiled wall in a Bristol cafe. The pattern in the image appears to show sloping grey lines between the black and white " tiles", but in reality the lines are parallel. This effect is due to the compromises that both the brain and the light receptors on the retina (back of the eye) have to make when image processing. There is no reason for the tiles to be black and white for the illusion to be achieve - it is their relative intensity which affects the outcome, not their colour

EDITORS COMMENTS
This print showcases the famous Cafe Wall Illusion, named after its discovery on a tiled wall in a Bristol cafe. At first glance, the pattern appears to depict sloping grey lines between black and white "tiles". However, this optical illusion deceives our perception as the lines are actually parallel. The phenomenon arises from the compromises made by both our brain and the light receptors on our retinas during image processing. The intriguing effect of this illusion is not dependent on the colors of the tiles but rather their relative intensity. It demonstrates how our vision can be easily tricked and manipulated through perspective and visual ambiguity. This fascinating interplay between psychology, neuroscience, and perception highlights how our brains interpret visual information. The Cafe Wall Illusion serves as a reminder that what we perceive may not always align with reality. It challenges us to question our assumptions about what we see and encourages us to delve deeper into understanding how our minds construct images. Science Photo Library presents this mesmerizing print as an exploration of illusory visuals and trickery in vision. Its intricate details invite viewers to ponder upon the complexities of human perception while appreciating the artistry hidden within scientific phenomena.
